Hey partner,
Here's my boat..

Note the 4 doors I cut out on each side of the seats..I would not have done this if this was not a heavy duty boat..I also took out all of the floatation styrifoam..to make room for life jackets etc..I ran a hidden jumper cable to the back of the boat under the floor's carpet so I can keep the battery in the back to balance my fat body..LOL

I had to put a 1 x 6 pressure treated in the back because the 4 HP Nissan was bending the stern..
